I don't know how you measure the memory usage, but I suspect that you do it
incorrectly. When you create a new tab you're also creating a new thread,
right? Now, in linux threads appear as seperate processes each
using the same amount of memory. But of course all the threads share this
memory--that's what the thread concept comprises.

When I start your application I get 40 new processes each "using" approx.
8MB. 40*8MB = 320MB. Is it that what you mean?

But, when measuring the overall memory usuage before starting your app and
when it's running I really just get a difference of about 4MB.

The growth of memory consumption nevertheless is certainly another problem
you need to resolve.
